A Florida woman, popular for her strong pro-gun stance, was accidentally shot by her 4-year-old son, authorities said on Wednesday.

Jamie Gilt, 31, was taken to a hospital following the shooting which occured on Tuesday, and is believed to be in stable condition. She is yet to make a statement to the police.

Authorities told CNN that the firearm was legally owned by Gilt, who maintained a Facebook page entitled “Jamie Gilt for Gun Sense,” where she regularly posted pro-gun positions. On her personal Facebook page, Gilt once bragged about her son: “Even my 4 year old gets jacked up to target shoot with the .22.”

Sheriff’s investigators are trying to determine how the 4-year-old boy had access to a gun he used to shoot his mother as she drove a pickup truck in north Florida.
